My employer, a university, just switched me to Microsoft Exchange from a POP3 based email server. They've disabled forwarding and POP3 access but allow IMAP access. In addition they have a very small disk quota.
I've used Gmail for years with lots of filters to access all my accounts. With 85GB of space, I've got lots of old email stored, and I search them often. Now I'm stuck.
The solution I envision is a personal mail server running in my office (on Windows XP or Linux) which accesses my email from Exchange via IMAP, and then allows Gmail to get it via POP3, or perhaps just forwards it. It would at some point also delete the email from the Exchange server so I don't go over my disk quota.
I won't be using Exchange's non-email functionality.
This program would also take mail sent by Gmail via SMTP and forward it on to Exchange via IMAP.
Does anything like this exist?
I know I could also use IMAP client software which could consolidate both accounts into a single client, but could I have access to all my emails from any browser and my Android phone?
